1. Is this request related to a challenge you're experiencing? Tell me about your story.

I am having trouble retrieving conversation history.
The API seems to be authenticated, but I wonder if the user_id is wrong.
If the user_id is wrong, can I check the user_id from the Didify screen?

import requests

url = 'https://api.dify.ai/v1/conversations'
params = {
    'user': 'bbd536bf-bbb4-4e48-9fc5-8814e4d2d4f6',
    # 'last_id': '',
    'limit': 20
}

api_key = 'my-api-key'
headers = {
    'Authorization': f'Bearer {api_key}'
}

response = requests.get(url, headers=headers, params=params)
print(response.json())

2. Additional context or comments

Hi! I'd like to know what should be the 'api_key' for the Bearer authorization? Is it created at the api access session that looks something like "app-xxxxxxxxxrIvdFJoi7N5y"? But when I tried it, the output of response.json() is: {"code": "unauthorized", "message": "Access token is invalid", "status": 401}.
